OIL CAN.

Application mea November 25, 1921. `semi No. 517,456.

is a full, clear,- and exact description of they same, reference being had t'o the accompanying drawings, and to the numerals of reference marked thereon, which form al part of this specification. j

This invention relates to an improved type of textile oiler or oil can, constructed to emit small quantities of thin oil through a spring controlled valve located at the outer end of the spout and adapted to be actuated by a force'pump mechanism operable bya lever.

It is an object of this invention' to provide an oil can constructed to eject drops or small quantities of oil from a valve controlled spout.'

It is also an object of the invention to provide an o'il can having a valve in the spout thereof adapted to be automatically closed to prevent leakage of oil from the can should the can be accidentally overturned.

It is a further object of this invention to provide an oil can, the cover of which is equipped witlr an operating lever which when operated, when the can is inverted, acts to cause oil to be forced by pressure through a spring controlled valve into the outer portion of the spout and then through a spring controlled outlet valve controlling the outer end of said spout.

It isfurtherrnore an object of the invention to" provide a spout cover for an oil can wherein the4 spout has a plurality of spring controlled valves therein adapted to be opened by al lever mechanism mounted on the cover.

Another vobject of the invention is to provide an oil can7 the' spout of which is provided with a pressure operated valve kadapted to permit small quantities of oil to be forced therethrough to be emitted through a valve'in the end' of the spout, said spout'valv'e adapted to be opened by operating a lever.

It is an important object of this invention t'o provide an oil can Aof simple and effective construction adapted particularly for emitting small quantities of thin oil successively through valve mechanisms mounted withinthe oil can spout and operable by means of a lever'A mechanism.

Other and further important objects of this invention will be apparent fron-1 the dis` closures in the drawings andspecilication.

The invention*k (in, a Apreferred form)l 1s illustrated on' the drawings and hereinafter more fully described. v

As shown on the drawings:

The reference-numeral l indicates ka can o-r container having anv integral neck cap comprising a coveri, the margin of which is bent to form a rim 6 adapted to loe removably engaged onthecan flange 4. A gasket or packing ring 7 is provided in the cover rime to form a tiglitvjoint between the can flange 4 and the cover 5. Integrally formed on the cover 5 is a cylindrical shell or casing 8 having rigidly secured thereinv by soldering or other suitable means the lower enlarged. end of a tapered oil spo'ut'lt).

.Projecting longitudinally through the spout 9.and the snellel is a valve stem 10 having an outlet valve Ahead 11 formedon the outer end thereof adapted to seat inthe end ofthe spoutfto close' the same; Secured on the lower Vor inner endo'f the valve stem l0 is a stop or clip- 12 against which the lower or inneren'd of a coiled spring 13 seats." The spring 13 swoundvaround the lowery portion of the `valve stem 10 and has the upper' end pressing'againstthe bottoni of a check valve plate 14. -The-chec`k valve plate has outlet aperturesl therein `and la middle opening through ,which the4 valve stem l0 projecten The check valvel plate 1.4 ifs-,provided with `an v'integral upwardly d1- rected rim orflange 16' whiclrcontactsthe inner surface of the spout shell 8 and abuts against the lower or inne-rendof the spout 9. Seated onf theioh'eck vvalve plate is a valve diskl'having a central opening through which the valvestem projects. A washer or clip 18 is secured on the valve stem above the valve disk 17. A coiled spring 19 is disposed Within the shell 8. The lower end of the coiled spring 19 seats against the flexible valve disk 17 while the upper end of said spring engages against the inner inclined surface of the lower end of the spout 9 as illustrated in Figures 1 and in the cover 5.

2. Engaged in the shell `8 below the valve plate 14 is a large coiled spring 20 the upper end of which seats against the bottom of the check valve plate 14 While the lower end of said spring 20 seats in a cup or plunger 21. The plunger 21 is slidably disposed within the lower or inner end of the cover shell`8 and has portions thereof cut away to afford inlet openings 22.

To hold the oil ejecting cup 21 in position to permit actuation ofthe same, the inner curved end 23 of an actuating or supporting arm 24 contacts with the bottom surface of said plunger 21. The outer end of the arm 24 projects through a spring washer plate 25 and through a slot 26 provided in an indented portion or socket 27 formed Movably seated within the socket 27 to cover the slot 2G and afford a non-leaking joint, is a curved washer plate 28 having an aperture therein through which the outer end of the arm 24 projects. Integrally formed on the projecting end of the arm 24 is a finger piece o-r lever 29. A portion of the lever 29 where it joins the arm 24 is curved as at 30 and is rigidly secured to the washer plate 28. To hold the washer 28 and' the curved portion 30 of the lever seated in the socket 27, a retaining -.member 31 is engaged on the arm 24, said member comprising a curved shank having a head 32 formed on one end and retaining lugs or clips 88 integrally formed on the other end and which are bent to engage around the arm 24 to. hold the retaining member in place., The head 32 of the retaining member is forced against the spring washer plate 25 and forces the same from the dotted line position of 1figure'4 to the full line position, thereby making the washer plate conform to the curvatures of the socket 27 and thus prevent leakage through theopening 26. The spring washer plate also acts, in conjunction with said member 31, to hold the washer plate 28and the curved portion 30 of the lever seated within the cover socket.

The operation is as follows:

The oil can is adapted to be filled with oil by removing the spout cover. The spout Ycover is thenlocked to the can l by friction retaining-mechanisms similar to the construction disclosed in Letters Patent No. 1,401,160, granted to me December 27, 1921, for improvements in lubricating cans.

Normally, the actuating lever 29v is held .plate 14 to close the apertures 15. With check valve and the outlet valve closed, leakage of oil from the spout 9 is prevented should the oil can bevaccidentally over-turned or left lying on its side.

To use the oil can, the same is turned to one side or inverted with the mouth of the spout 9 engaged in or upon a. device or mechanism requiring lubrication. The oil in the can is thus permitted to flow through the openings 22 into the plunger 21 and into the chamber within the shell 8. `The' lever 29 is now depressed thereby rotating or moving the washers 25 and 28 with respect to the cover socket 27 and at the same time causing the arm 24 to move in the slot 26. The inner end 23 of the arm 24 is thus swung upwardly, thereby forcing the plunger 21 into the shell 8. Inward movement of thel plunger causes oil to be trapped therein and also causes compression of the plunger control spring 20.

As the plunger moves outwardly or into the shell 8, the trapped oil 'being under pressure is forced through the check valve openings 15, thereby slightly lifting the check valve disk 17 against the action of the check valve spring 19. A small quantity of oil is thus forced into the spout 9 and ows outwardly toward the mouth of the spout 9. lith the movement of the plunger into the shell 8, the bottom of said .plunger is brought. into Contact with the inner end of the outlet valve stem 10 and forces the same outwardly compressing the spring 13 and opening the valve A11. Oil in the spout 9 is thus permitted to flow by gravity from themouth of said spout. I

lVhen the lever 29 is released, the spring 2O returns the plunger 21 from the position shown in Figure 2 to normal position, kthereby also causing the lever mechanismto be returned to the normal position illustrated in Figure 1. The spring 13 acts automatically to pull the valve stem 10 inwardly, thereby closing the discharge valve 11. The check valve disk 17 is closed by the spring 19, therebyv closing the apertures 15 in the check valve plate 14. s

In the textile business, it is necessary to use an oil can adapted to emit small quantities of very thin oil. The check valve mechanism within the enlarged lower portion of the spout permits only smallv quantities of oil to pass therethrough into the outer portion of the spout 9 to be emitted through the outlet or discharge valve l1.

I am aware that numerous details of c-onstruction may be varied through a wide range withoutl departing from the principles of this invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

I claim as my invention:
